I believe we are to find for values in this problem.
a. The graph of the function
b. The domain and range
c. The slope
d. The c intercept value
Answers:
a. see the graph photo attached
b. The domain is the set of all x that can be input to
the function. Since x is the distance and we know that distance cannot be
negative hence the domain is:
x ≥ 0
So the range starts from x = 0:
c (x) = 0.5 * 0 + 70 = 70
Therefore the range is:
c ≥ 70
Domain: x ≥ 0 Range:
c ≥ 70
c. A linear equation has a general form of:
y = mx + b
where m is the slope
From the given equation, the slope is 0.5.
slope = 0.5
d. The c intercept is simply the value of c when x is
equal to 0
c intercept = 70
